Q700 Hot Dip Galvanized Square Tube, 20x20 and 25x25 mm Requirements
Galvanized square steel tube has an actual 0.5–6.5 mm wall range or custom, combined with 6, 6.4, 12 m and customized length choices. Described sections include 20x20 and 25x25 mm.
Confirm exact Q700 material because the accompanying grade list identifies other structural steels. Choose the complete square or rectangular section and a feasible measured wall thickness rather than assuming every dimension can be combined. Define hot dip galvanizing acceptance separately.
The Z20–Z600 surface code has no area unit and requires interpretation before comparing zinc requirements. Non-oiled supply is described, but no numerical strength or pressure result is supplied. General construction, boiler and fluid uses do not establish a load rating, operating pressure or verified certificate for the selected tube.
